Houthis launch missile at tanker in Red Sea
Yemen's Houthi rebels launched a ballistic missile that landed near an oil tanker in the Red Sea on September 1, 2025. The Houthis claimed the target was the tanker Scarlet Ray off the Saudi port of Yanbu. The same day, a Singapore-flagged tanker collided with a Malta-flagged bulk carrier off Tanah Merah with light oil sheens reported, and a pirate attack on a chemical tanker off Togo was reported.
